The firm announced that it would be releasing Portal 2 on the system after previously focusing on the PC and Xbox 360 during development.

"PS3 is incredibly important to us. We don't feel that the PS3 users had the Valve experience that we like to deliver," product manager Erik Johnson told CVG at gamescom.

"So in that case it's incredibly important to us; we kind of fix everything wrong in the products that we delivered before for the PS3, which we thought were good but weren't quite the Valve experience."

He added that bringing Steamworks to the system would help avoid problems previously seen in The Orange Box.

"We're looking forward to solving that and having Steam on that platform also is incredibly valuable to us," he said.

"In a lot of ways that is the way we define a customer having a good experience because it's the way that we keep talking to that customer over time."

Portal 2 will also be available for Xbox 360 and PC on February 9 2011.
